JHW To all whom it may cancer 2i:

Be it known that I, ALLAN L. MoGnnoon, a citizen of the United States, and a restdent of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bumper-F ttings, of which the following is a specification. I p

This invention relates to automobile bumpers, and more'partic't arly to a fitting designed to be built into the forward end. of a motor vehicle frame and to form a permanent part thereof, such fitting; including; not only the ordinary spring bolt mounting, but alsoian arm especially designed. to support. a bracket by which a bumper may be readily attached to the vehicle.

oil

\ vention, these drawings being The present development of automobile manufacture has reached a point Where a .bump'er'is becoming recognized as a stand ard equipment, although no especial ai' rangement has been provided foi mountmg bumpers to the frame of a vehicle, other than by different types of attaching brackets which are clamped or otherwise counected to the frame members at the forward or rear end of the vehicle. The result has been that manufacturers of bumpers have been compelled to devise various types of attaching brackets in order that their bump ers may be readily attached to different makes of motor vehicles.

The purpose of the present invention is to provide afitting adapted to be built into a motor vehicle frame, and to form an integral part thereof, in order that bumpers may be readily applied Without resorting to the use of separate attaching members, to the end that the bumper becomes an integral part of the vehicle rather than an at tachment applied in a more or less insecure manner. 4

In the drawings is illustrated a preferred construction for a fitting embodying the inbriefly 'rescribed as follows:

Figure 1 is a top plan view ofa convenient type of bumper attached to the frame members of a motor-vehicle, through the medium of the fittings embodying the in.

vention,

Application filed January 17, 1921. Serial No. 437,737.

Fig. 3 is an enlarged View in side elevation of the parts shown in Fig. 2 and Figs. 4 and 5 are vievvs corresponding to Figs. 2 and 3, and illustrating a modified construction of the fitting.-

\Vithout describing in detail'the bumper illustrated in Fig. 1, the same may be considered to be typical of the large class of bumpers which comprise a front bar or in pact section A, and a rear bar B, which has direct connection with the brackets or taching members by Which the bumper mounted at the {forward ends of the lon jg' tudinal frame members or sills (I O of motor vehicle./

It is the common practice in forming the frame members or sills (7-4} of a motor vehicle, to form enlargements or heads at the extremities. of these frame meml'iers Which act in the nature of a housing to reserve the extremity of the spring, the parts being connected together by means of the spring belt which passes through the head ingr, comprising in general three portions;-

namely, a'shanlr 2, a head 3 and a nose 4;. all these portions forming integral parts of the complete fitting. The shanlr portion 2 is shaped to confornrwith the curvature of the end portion of the sill C, and to fit with in the channel formed between the horizon tal Webs 5-5 tl'ierco'f. As clearly shown in Fig. 2. the shank portion 2 has flat bearing nt With a vertical Web 6 oi the .n'g one face... the opposite surface of the shank being tapered toward the rear or lilxtendiugr" transversely through the shank and at several points therealong, are a series of rivets; 7, which also pass through the vertical Web 6 of the sill C. In addition to the horizontal rivets, eiiother rivet 8 may be extended tran versely through the shank 2, and the horizontal Webs 5-5 of the sill. In this manner the shanlr'of the fitting is permanently cured to the end of each sill C. The head it M opposite ends. 1

openings are located in the end 'rralls 3 lindric member having the same conforma tion as is ordinarily employed in motor vehicle constructions; namely, a c 'lindi'ic Wall 3 extending throughout the -orward portion of the head, and end walls 3" at the Two horizontally alined through which a spring bolt 9 extends, said bolt being surrounded within the head 3 by the eye or looped end 10 of the upper leaf of the vehicle spring 11. As clearly shown in Fig. 3, a portion of the cylindrio Wall is removed throughout the under side or" the head to pit'ovide an opening to permit the insertion of the eye of the spring. in addition to the parts already mentioned, the spring bolt is held in place by the usual nut 9 and spring washers 9*. Furthermore, a bushing 12 may be inserted between the spring bolt and the looped end of the spring,

I is the ordinary practice.

silsrtending forwardly from the head 3 is the linked comprising a vertically disposed block havinga vertical bore l uI'BfOl. adapt ed to receiveapivot bolt 13. Pivotally connected to the projecting ends of the fitting is a clamping block 1 comprising an. in verted U-shaped portion 15 adapted to have clam in en' a ement with the rear bar ll of the bumper, the clamping engagement being maintained by means of a cap screw 16 extending through the parts of the El shaped portion 15 net below the bar-B. The clamping block 14. further comprises-fiver. cally spaced ears 17-17 extending from the rear face or: the ill-shaped portion 15, and embracing the nose 4 of the fitting, these ears being provided with registering bores adapted to receive the bolt 13, thus forming a pivotal connection between the clamping block 14 and the forward end of the fitting, the former having rotative' movement about the vertical axis.

in Figs. Q and 5 is shown a modified vonstruction for the fitting, wherein the some construction is employed so turns the shank and head. portions 2 and 3 respectively, are concerned, but (littering somewhat in the naanner in which the clamping block is pi"- otallycounocted to the forward, end of the fitting. Instead of employing a nose or projecting block at the forward end of the fitting 2, ears 18-18 extend forwardly from the upper and lower portions of the head 3, these ears supportinga vertically disposed bolt 19 as before, and embracing between block 21. As before suggested,

them a lug 2O integral with the ampin the parts vice versa, with l i-poet to the (humping block 21.

In adaptingthe lin for use a: all intogro-l part of a. motor vehicle frame, the same would ordinarily' include the Usbapcd clamping block so lha? any type oi bumper inay be readil applied. providingzj it bad a portion which would fit within the U-shapcd portion of the vlemipiiu; block. On the other hand, the variety of lz-umpers that may be applied to the vehicle. can readily be increased by using; a ranging block of slightly diilcrent sh any event. the vehicle is provid .d wui mbcr specially designed For ti alta clnncnt of a bumper. thereby cliinina the necessity of drilling; holes through taclrnne member. or muti lating the s )lash pans or adjmjcnt parts in order to attach :1 blnnper to the vehicle. Furthermore, it eliminates the addition in weight one to the use of culnberson'ie attaching members, and the uucertaiutv of a pernninent connection, which must be present where frictional and clan'zping connections are used.

Havingdescribed a preferred construction for a fitting; fulfilling the purpose set forth. I claim as my invention:

l. A. fitting :ulaptcd to be permanently fixed to the end of a vehicle frame member. and comprisiu; a. head projectingbeyond the end of the frame niemlwsr. and an into gral support for a bumper.

2. A fitting adapted to be pcrnnmouily connected at the end ol" :1 vehicle frame member, and comprising a shank portion tending lengthwise of said l'ramc mcinbcr. n

l. A lilting adapted t e-lie 'pcrmlincntly' connected ut 'thc endv of a vehicle framernenibcr. a d comprisinga shank portioi'i extending .iigitudinally oi the frame mem' her, a head portion located beyond the end of the frame member. and. forming a support for the spring; bolt, and a nose portion projecting iilutwardly from said head. and a clamping block pivotally comiected with said nose. I

#2. A. bumper attaching; fitting adapted to be permanently built into the end of a rehicle frame member, and comprising: a shank portion adapted for overlapping couucctiou with said frame members, a head beyond the end of the frame member, and a sup 'iort for a bumper integral with. said head. A

A fitting adapted to be permanently connected at the end of a vehicle frame member, and comprising a tapered shank portion extending longitudinally of the R frame member, a head formed beyond said shank, and forming a support for the spring bolt, and a nose portion projeeting outwardly from said head, and a clamping block pivotally connected with said nose.

In witness whereof, I hereunto subscribe 10 my name this 11th day of January, A. D. 1921.
